How to create the reference axis for a 3D tube from the .STP file?

Yogesh Channaiah Oct 7, 2014 2:29 AM

I have a model of a 3D tube which is in .STP format. Now I want to create a axis for that tube, so that I can follow the same path to sweep with a different contour.

How can I do it? I tried to create the axis using reference axis command, but it didn't worked because the tube is a 3D tube, where as reference axis command works for only single plane!!!

Pls help.

hei'ya Yogesh,
maybe if you post your file,
using the advanced editor-top right of the reply pane
and attach button-bottom right of pane>browse to file,
members can see your problem and suggest their solutions
have a good'n kelef

    hei'ya Yogesh,
    see the scrnsht below with shell command
    
    this is with SW14- 3D_tube.SLDPRT att-file-download and unzip
    hope this is of some help to you- have a good'n kelef

      Hi Kelef,
      I'm using solid works 2013, So I don't have 3D shell command.
      And also I cannot open your attached file. Isn't there any other ways

        So I don't have 3D shell command.>
        
        There is nothing like 3d shell, it is the shell feature on the feature toolbar OR Insert > Features > Shell

      I don't believe it is possible to exactly replicate the sweep path through that part because the geometry is distorted at the intersections of the 'rings' and the sloping portions, and will not be a true cylindrical form through that region.
      
      The best bet would be to remove those regions and rebuild with the correct geometry.

        Hi Kelvin,
        But how do you determine the sweep path?

    Start a new 3d sketch, using convert entities, convert all tangent/circular edges. Now using lines/arc, connect their center point to the required sweep path.

      bump Deepak,
      I really need to read the questions twice or three times,
      misunderstood yet a simple difference the sweep line I guess
      have a good'n kelef

      I tried this, but it is not working.
      As I convert two semicircles, I won't get a center point.
      Also I can't join the center points, such that the line joining them is along the axis of the cylindrical tube.!!

        But you can't create the axis when there is no straight lines on either sides..right?
        Also i need to follow the exact path of the tube!!!!
        Is there any other way??

        You can use arcs in those cases.

        Sir,
        Pls tell me in detail.
        How could you use arcs when there the two points are in different planes, but have to follow a specific path.
